To all whom it may concern: 7 Be it knowni bllat BENJAMl-N F. L'BELLQWs,

and useful Improvements in Slug-Ejecting Mechanism for Line-Casting.Machines, of which the follow-ing is a specification. I

This invention is intended for use as part of aline castingtypographicmachine y that isto-say, a machine-by whichtypeiloars or slugs a'recastin a: mold slot Whose :front face is closed by an: assembled line ofmatrices. V L In machines" of this character the type bars are 'pu'shedout of the mold slot andl between trimming knives by an ejector bladewhich engages'that edge; of the type bar or slug which is thebottom-edgewhen the slug is in use; I V I Machines of this "sortareadapted to use an'd do'usemolds having slots of different:

sizes.1It-ispractically necessary that the ejector blade I shall prettynearly; fill the mold slot as it'pushe's the typebarout. It

isfurther necessary 'to use, from time to time, avarietyof ejectorbladesawhioh mustf vary as to width, andmaywvary asto thicknessyso thatthe ejector in' use shallalways correspond with the dimensions-=oftheslot of the mold in use.

T heobjectof thisin'vention is to provide in a machine of-thissor'taplurality of one piece ejectors having blades suitable for: use

at different times "and: with difierent molds, together; with meanswhereby .any ejector, blade may be readily brought into operativerelation with the mold and with the mechanism by which the selectedejector-blade may be operated. I p

The invention consists in thecombination of parts shown in the drawingand hereinafter described and pointed out defi nitely in the appendedclaims.

In the drawing, Figure 1 is a front elevation of a mold disk and theejector mechanism behind it,the mold which will be in the ejectingposition having been removed from the mold disk; Fig. 2 is a sideelevation of the present invention and some associated parts; Fig. 3 isa side elevation, and Fig. 4

is a front view of the ejector operating slide. Fig. 5 is a sideelevation of an ejector and RQ ea 1a a 1e a ar: rat 'nteanec: 18.11917.-

diski as shownxin Figz l'isrin the casting H position," that is to sayl-infthe positionto} haye'the-front side ofthei mold slot -a closed loya:v line Jofmatrices', and-- to: have molten? metal injecte'd into itsrear side. The mold which fitsninr and oventhe hole'al in the;mold'di'skustftogthe left of the upper mold intFigz 1 would be in the-ej'ecting posi-tion, that =i s, ='the position it' would occupy inorder that the to-be-described ejector mechanism may slot. V

The mold diskmay beturned by'any suitable mechanism, 1 which has-nothingvtoi do push a' slug-forvvard outof the *mold with thepresentinventi'on; and -the mold disk may be adapted for adj ustme'nt''so' t-h'at any one of the molds'securedthereto, in the ordinaryoperation; of-the machine; will be move'd back and forth between the Tcasting and ejecting-positions,- as; described. The

mold disk-as shown carries-five molds,- but it -mi ghtcar r-y anydesired number and the mold slots-:01 the several molds maybeof varioussizes dependinguponthe character of the Workwhich the, machine is'-'tempo-- rarily equipped for doing; Because-the mold" disk" carries fivemolds as shown, it-is desirable that there-should be fiveejector's Beach fitted to ootiperatewith one of these molds".

Inthe constr'uction shown five F of -such ej ea tors "are showm -and tleyare'slidably mounted in an ej ect'o'ri magazine D which is pi v fiotally suspended from -the shaft F," which may be a shaft having otherfunctions, or a shaft especially provided for" the purpose. Each ejectorcomprises a body I; (and all of these bodies are preferably the samesize) and a blade I) which is preferably formed integrally with thebody, and projects forward therefrom. All of these blades are of thesame length, but they vary in idth and may vary in thickness, asrequired. Some may be narrower than the body, one the same width, andone or more may bewider.

top and bottom edges, and these are slidably mounted in guide grooves din the upper and lower members of the ejector magazine. These ejectors,when so mounted, occupy nearly parallel positions, although theyactually occupy positions which are radial with respect to the axisabout which said magazine may swing.

The ejector magazine may be swung into positions to bring any desiredblade into operative relation, that is to say, into alinement with theslot of that mold which is in the ejecting position. To so move themagazine a rocking sleeve G is mounted in suitable fixed bearingsconcentrically with the shaft F. This sleeve, at its rear end, is formedwith an arm 9 that is pinned to the frame (F of the ejector magazine,whereby the magazine must rock with. said sleeve. This sleeve alsocarries a handle 9 by which it may be rocked; and is provided with adownwardly extended arm 9 having near its lower end a hole through whichthe index pin K may pass. This arm 9 passes between two parts a a of thefixed frame of the machine, and in these parts are five index holes 02By putting the index pin in the proper holes a a, and through the holein the arm 9 the ejector magazine will be fixed in the desired position.

When any ejector is in operative relation with the mold, it is likewisein operative relation with the ejector operating slide M. This ismounted in dovetailed guideways so as to be movable forward andbackward; and is associated with suitable mechanism, which may besubstantiallylike that shown in Letters Patent No. 1,080,570. A partonly of the mechanism shown in that patent is shown in Fig. 2 of thedrawing of this application, viz., a lever P having a pin 79 at itsupper end; and a hook R which is pivoted to the slide M and engages saidpin. The lever P is positively rocked backward and forward, therebymoving said slide, by two cams T T with which two arms 7) p respectivelyengage. A plate m which projects forwardfrom and is rigidly fastened tothe slide M has a T-shaped tenon m which may easily enter a T-shapedmortise Z1 in the rear end of the body part of each ejector. This slideM is so placed that said T-shaped tenon 122. will be in the notch 6 ofthat one of the ejectors which is in operative position. This comesabout in part from the location of said slide, and in part because, asthe ejector magazine is swung about its pivotal support, the T-shapedcross mortises in the several ejectors go'over said T-shaped tenon,wherefore, when the ejector magazine stops and is fixed in position, theT-shaped tenon m is in the T-shaped mortise of that ejector which is inoperative position with respect to the mold.

Having described the said invention, I claim: I

l. Ejector mechanism for typographic machines comprising, incombination, a mold, ejector operating mechanism which includes a guidedslide adapted'to engage with any ejector which is brought into alinementwith it, a pivoted ejector magazine located between said mold andejector operating slide, a series of ejectors slidably mounted in saidmagazine,said magazine being capable of swinging to bring any ejectortherein into operative relation with the mold and with the ejectoroperating slide.

2. Ejector mechanism for typographic machines comprising, incombination, a mold, ejector operating mechanism which includes a guidedslide adapted to engage with any ejector which is brought into alinementwith it, a pivoted ejector magazine located between said mold andejector operating slide, a series of ejectors slidably mounted in saidmagazine,-said magazine being capable of swinging to bring any ejectortherein into operative relation with the mold and with the ejectoroperating slide, and means for locking said magazine in any operativeposition.

3. A slug ejecting mechanism for linotype machines having a plurality ofejectors mounted on a common axis and adapted to selectively cooperatewith the mold disk.

In testimony whereof, I hereunto atfix my signature in the presence oftwo witnesses.
